MECHANICAL MOVEMENT.

Application filed April 11, 1895.

To aZZ whmn it may concern.-

Be it known that we, LEONARD C. GILLETT and ULYssEs G. GILLETT, citizensof the United States, residing at Brownsdale, in the county of Mower andState of Minnesota, have invented certain new and useful Improvements inMechanical Movements; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention is an improved mechanical movement or motor fortransmitting the power through a windmill to an engine or other form ofmotor.

The object of our invention is to provide a contrivance by which thereciprocating motion of the windmill-rod can be transformed into arotary motion for driving a crankshaft or pulley, and a further objectis to provide a system of lovers which will avoid all deadcenters andtransmit the power in a quick, easy, and steady manner.

Vith these and such other objects as may appear farther on our inventionconsists in the peculiar construction of the various parts and theirnovel combination or arrangement, all of which will hereinafter be morefully described, and pointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is a faceview of our improved motor or engine. Fig. 2 is a sectional view on thelines 2 2 of Fig. 1.

In carrying out our invention we employ a suitable vertical support A,which may be made of wood or metal, as desired. Attached to said supportis a guide B, through which works the pump-rod O, the lower end of saidpump-rod being connected with the lever D, which is pivoted centrally toa cleat E, attached to the support A. Depending from this cleat E is aswinging link F, said link being made double, as shown, and between themembers thereof is pivoted a lever G, the upper end of which connectswith one end of lever D, while the lower endis adjustably connected withthe pitman H hereinafter referred to. At the point of connection betweenthe lever D atent No. 553,581, dated January 28, 1896.

Serial No. 545,364. (No model.)

and pump-rod C is attached a pitman K, said pitman extending through aguide L, mounted upon the side of the lever G, and at its opposite endis connected with a lever M pivoted upon the main pitman N, the oppositeend of said lever M being connected with the pitman H before referredto. Above and below the pitman K and near the guide L are thecoilsprings O O, the purpose of which is to assist in throwing thelevers D and G and pitman K to one side or the other, and thus avoid anydead-centers. The main pitman N is connected with the lever G at thepoint of attachment to the swinging link F. The lever M is pivoted uponthe main pitman N, and the pitman H and lever G are adjustable throughthe medium of a series of perforations and the locking-pin. The lever Mand pitman K are also adjustable in the same manner. The main pitman Nis connected with the crankshaft P, crank-disk or pulley, and transmitsthe power thereto in such a manner as to revolve the same, thustransforming the reciprocatin g motion of the pump-rod into a rotarymotion.

In operating the device by the downstroke of the rod O the end of leverD connected therewith will be forced down and the end connected with thelever G moved upward. At the same time the upper end of the lever G isthrown rearward and the lower end of the said lever is thrown forwardand the pitman K is also moved slightly forward. The lower end of thelever G moving forward throws the pitman H forward also, and the lever Mis caused to rock slightly upon the pitman N, but as a whole said pitmanN is moved forward and with it the lever M. Upon the downstroke of therod 0 the lower spring 0 is compressed by the pitman K, and the momentthe pitman N has passed the center said spring 0 tends to expand andthrow said pitman K upward upon the upstroke of the rod 0.

The operations of the levers D, G, and M, as well as the pitmen K, H,and N, are the reverse of those above indicated when the rod 0 is movingupward.

Having thus described our invention, what We claim, and desire to seenre by Letters Patent, is-

111 a mechanical movement, the combination with the rod 0, of the leverD, link F, lever G, pitmen II, K, and N, the loop L, springs O, andlever M, and the crank shaft or disk P all arranged substantially asshown and described.

In testimony whereof We affix our signatures in presence of twoWitnesses.
